The following ant task will be found in the shib build file:

        <javac srcdir="${src}" destdir="${build}" includes="**/*.java"
debug="on"
                target="1.4" source="1.4">
            <classpath refid="build.path" />
        </javac>

I recommend you delete the -target option:

        <javac srcdir="${src}" destdir="${build}" includes="**/*.java"
debug="on"
                source="1.4">
            <classpath refid="build.path" />
        </javac>

Although not conclusive, experiments seem to indicate that the -target
option is responsible for the following wierd error:

Also, perhaps you might want to add a <compilerarg> element to the compile 
task:

        <javac srcdir="${src}" destdir="${build}" includes="**/*.java"
debug="on"
                source="1.4">
            <classpath refid="build.path" />
            <compilerarg value="-Xlint" />
        </javac>

This gives verbose but interesting details about the compile.
